The Sentinel 150, 24V, 5A Battery Charger provides high performance charging for continuous float charge and standby power applications. It is configured for fast, accurate charging, to give optimum battery life and reliability. Smooth output allows charging of sealed or vented batteries, or use as a stand-alone power supply.

The Sentinel 150 features an intelligent, multi-stage charge regime: during charge recovery mode, the Sentinel gives a constant (maximum) current output; as the battery approaches peak charge, the output reverts to float charge mode, maintaining an optimum cell voltage and supplying additional standing load current up to the rated maximum. Output current is always limited to the rated maximum, even during high load (e.g. engine cranking), short-circuit or reverse polarity connection.
